Product Description

NU-CALGON 4770-0 50P Poly Sprayer Coil Gun

Durable Polyethylene Construction

The No. 50P Poly Sprayer Coil Gun is molded from high-density polyethylene for chemical resistance and long service life. Its 0.5-gal (3 pt) tank withstands acid-based coil cleaners without cracking.

Adjustable Spray & Flow Control

An adjustable nozzle offers a full range of patterns—from jet to fine mist—while a thumb-lever lets you modulate flow rate precisely for consistent coverage.

Built-in Air Pump

The integrated 7″ polyethylene pump pressurizes the tank in moments—about 20 plunger strokes at full capacity—to deliver up to 50 psi of spraying pressure. Additional strokes recharge pressure mid-job.

Versatile Cleaning Applications

Compatible with CalClean®, Special HD CalClean®, Alka-Brite® Plus, Nu-Brite®, and other Nu-Calgon coil cleaners, it tackles air-conditioning coils, condensers, heating coils, refrigeration coils, and permanent filters—ideal for professional maintenance.

Features and Benefits

  • Durable polyethylene construction.
  • Three pints of working capacity.

Additional Information

Directions

  1. Visually inspect sprayer and ensure that the sprayer is in good working order.
  2. Remove the pump assembly from tank by turning it counterclockwise.
  3. To minimize foaming when preparing cleaning solution, add water to the tank before adding the Nu-Calgon coil cleaner. Fill tank to the desired level, not higher than the top (1.5L) mark on side of tank.
  4. Close tank by inserting pump assembly through opening. Tighten cap clockwise until pump is sealed tightly into the tank (hand-tighten only).
  5. Pump plunger to compress air and create pressure in tank. When tank is full (1.5L mark), 20 strokes will provide a good working pressure. As pressure drops during use, recharge with 6-10 or more pump strokes. More strokes will be needed if the tank is not full. Note that excessive pressure can result in unwanted spray drift.
  6. Nozzle tip may be adjusted to provide a single- needle stream (tip screwed all the way out) or a fine mist (tip screwed all the way in). The needle spray should be used on finned coils to reach the third and fourth banks better. Mist is better for cleaning permanent filters.
  7. Allow cleaning solution to remain to contact with dirty surfaces for about 15 minutes, then flush with water from a hose. If a hose is not available, fill sprayer with water and flush using a coarse spray.

This product must be used in accordance to the following directions by HVACR professionals only.
